Lisåksi menetelmå liittyy poly(aryleenisulfidike-toneihin), jotka on valmistettu alkalimetallivetysulfidin ja alkalimetallihydroksidin reaktiotuotteesta. Edelleen keksinto liittyy poly(aryleenisulfidiketoneihin), jotka on valmis-10 tettu kåyttåen alkalimetallisulfidia ja alkalimetallive- tysulfidia. Keksintd liittyy myos kuituihin ja muihin tuot-teisiin, jotka on valmistettu nåistå poly(aryleenisulfidike-toneista).The invention relates to a process for the preparation of poly (arylene sulphide ketones). In addition, the process relates to poly (arylene sulfide ketones) prepared from the reaction product of an alkali metal hydrogen sulfide and an alkali metal hydroxide. The invention further relates to poly (arylene sulfide ketones) prepared using alkali metal sulfide and alkali metal hydrogen sulfide. The invention also relates to fibers and other products made from these poly (arylene sulfide ketones).
15 Poly(aryleenisulfidiketonit), PASK, ovat tårkeå luokka tek- nisiå kestomuoveja. Poly(aryleenisulfidiketonit) ovat kau-pallisesti kiinnostavia kåytettåvåksi kalvoihin, kuituihin, puristeisiin ja komposiitteihin korkeiden sulamispisteidenså vuoksi. Yksi menetelmå poly(aryleenisulfidiketonien) tuotta-20 miseksi kåsittåå dihalobentsofenonin, kuten diklooribentso-fenonin, reaktion alkalimetallisulfidin kanssa. Alkalimetal-lisulfidi saadaan alkalimetallivetysulfidin ja alkalimetallihydroksidin reaktion tuloksena kåytettåesså kåytånnolli-sesti katsoen tarkkoja ekvimolaarisia mååriå (stokiometrisiå 25 mååriå) alkalimetallivetysulfidia suhteessa alkalimetalli- hydroksidiin, koska kummankin osatekijån ylimååråå on pidet-ty epåtoivottavana.15 Poly (arylene sulfide ketones), PASK, are an important class of technical thermoplastics. Poly (arylene sulfide ketones) are of commercial interest for use in films, fibers, extrudates and composites due to their high melting points. One method of producing poly (arylene sulfide ketones) involves the reaction of a dihalobenzophenone, such as dichlorobenzophenone, with an alkali metal sulfide. The alkali metal sulfide is obtained as a result of the reaction of an alkali metal hydrogen sulfide and an alkali metal hydroxide using practically exact equimolar amounts (stoichiometric 25 amounts) of alkali metal hydrogen sulfide relative to the alkali metal hydroxide, since both components are in excess.
Kuitenkin poly(aryleenisulfidiketonien) suurin haittapuoli 30 on ollut suhteellisen pieni molekyylipaino. Mieluisinta olisi kyetå tuottamaan poly(aryleenisulfidiketoneja), joilla on suhteellisen suuri molekyylipaino. Suuren molekyylipainon omaavilla poly(aryleenisulfidiketoneilla) on yleenså parempi iskunkeståvyys ja jåykkyys verrattuna pienen molekyylipainon 35 omaaviin poly(aryleenisulfidiketoneihin).However, the major drawback of poly (arylene sulfide ketones) has been its relatively low molecular weight. It would be preferable to be able to produce poly (arylene sulfide ketones) with a relatively high molecular weight. High molecular weight poly (arylene sulfide ketones) generally have better impact resistance and stiffness compared to low molecular weight poly (arylene sulfide ketones).
Tåmån keksinnon kohde on tuottaa menetelmå suuren molekyylipainon omaavien poly(aryleenisulfidiketonien) valmistami- 2 seksi. Toinen keksinnon kohde on valmistaa suuren molekyyli-painon omaavia poly(aryleenisulfidiketoneja).It is an object of the present invention to provide a process for the preparation of high molecular weight poly (arylene sulfide ketones). Another object of the invention is to prepare high molecular weight poly (arylene sulfide ketones).
Nyt on keksitty, ettå suuren molekyylipainon omaavia poly-5 (aryleenisulfidiketoneja) valmistetaan saattamalla reak- tioseoksessa, mieluummin polaarisessa liuottimessa, koske-tukseen toistensa kanssa polyhalobentsofenoni ja alkalime-tallivetysulfidi, jota on låsnå pieni, mutta tårkeå, tarkas-ti mååråtty måårå alkalimetallisulfidin stokiometriseen måå-10 råån nåhden, joka tarvitaan kondensaatiopolymeroinnissa.It has now been found that high molecular weight poly-5 (arylene sulphide ketones) are prepared by contacting a polyhalobenzophenone and an alkali metal hydrogen sulphide in the reaction mixture, preferably in a polar solvent, with a small but important alkali metal. måå-10 råån required for condensation polymerization.

Esimerkki II. Tåsså esimerkisså kuvataan PPSK:n valmistamis-10 ta olennaisilta osin Sarjan 1 (Esimerkki I) menetelmån mu-kaisesti kåyttåen Na2S-hiutaleita (mieluummin kuin NaSHrta tai NaOH:ta). 56,88 g natriumsulfidihiutaleita (jotka sisål-sivåt noin 59,3 painoprosenttia Na2Sråå, noin 1,3 painopro-senttia NaSHrta ja noin 39,4 painoprosenttia H20:ta vastaten 15 0,432 moolia Na2S:åå ja 0,013 moolia NaSHrta ja 1,25 moolia vettå) saatetaan reagoimaan 0,432 moolin kanssa DCBPrtå NMP:n låsnåollessa, jota oli 3,46 moolia.Example II. This example describes the preparation of PPSK essentially according to the method of Series 1 (Example I) using Na 2 S flakes (rather than NaSH or NaOH). 56.88 g of sodium sulfide flakes (containing about 59.3% by weight of Na 2 S, about 1.3% by weight of NaSH and about 39.4% by weight of H 2 O, corresponding to 0.432 moles of Na 2 S and 0.013 moles of NaSH and 1.25 moles water) is reacted with 0.432 moles of DCBPr in the presence of 3.46 moles of NMP.
Låsnå oleva NaSH vastasi noin 3 %:n ylimååråå NaSHrta. Muo-20 dostuneen PPSK-hartsin (saanto noin 89 g) sisåinen viskosi-teetti oli 0,58.

The intrinsic viscosity of the molded PPSK resin (yield about 89 g) was 0.58. Therefore, the use of an alkali metal sulfide such as Na 2 Sm and a certain small excess of alkali metal hydrogen sulfide such as NaSHm is clearly effective in the field of application of this invention.

This example illustrates the vulcanization of PPSK in such a way that its molecular weight continues to increase. The dark resin prepared in series 6 was placed in a drying oven heated to 316 ° C. The intrinsic viscosity of polymer 30 increased from an initial value of 0.68 to 0.84 after 30 minutes and to 0.97 after 60 minutes. After heating for about 120 minutes, the polymer no longer dissolved in H 2 SO 4. It was found that during the vulcanization, gas was evolved from the polymer, especially during the first 35 hours.
